Refraction of TM 01 radially polarized mode from a chemically etched fiber
نویسندگان
چکیده
We propose a method for producing and controlling a radially polarized beam based on the lateral refraction of the TM 01 mode from a fiber after chemical etching of the cladding. Two aspects are studied: (1) the quality of the refracted beam as a function of the geometry of the etched segment, (2) the method of polarization control by a series of azimuthal detectors. The polarization is modified by a stress controller classically used with single mode fibers.

Radially polarized conical beam from an embedded etched fiber.
We propose a method for producing a conical beam based on the lateral refraction of the TM(01) mode from a two-mode fiber after chemical etching of the cladding, and for controlling its radial polarization. The whole power of the guided mode is transferred to the refracted beam with low diffraction. Polarization control by a series of azimuthal detectors and a stress controller affords the tran...
متن کاملAll-fiber controller of radial polarization using a periodic stress.
Our aim is to transpose the polarization control by mechanical stress, usually applied to single-mode fibers, to the (TM(01), TE(01), HE(21)(ev), HE(21)(od)) annular mode family. Nevertheless, the quasi-degeneracy of these four modes makes the situation more complex than with the fundamental mode HE(11). We propose a simple device based on periodic perturbation and mode coupling to produce the ...
متن کاملRadially and azimuthally polarized nanosecond Yb-doped fiber MOPA system incorporating temporal shaping.
We report an Yb-doped fiber master-oscillator power-amplifier (MOPA) system with the capability of selectively generating doughnut-shaped radially and azimuthally polarized beams with user-defined temporal pulse shapes. The desired output polarization was generated with the aid of a nanograting spatially variant half-waveplate (S-waveplate). The latter was used to convert the linearly polarized...
متن کاملSimple coherent polarization manipulation scheme for generating high power radially polarized beam.
We present a simple novel scheme that converts a Gaussian beam into an approximated radially polarized beam using coherent polarization manipulation together with Poynting walk-off in birefringent crystals. Our scheme alleviates the interferometric stability required by previous schemes that implemented this coherent mode summation using Mach-Zehnder-like interferometers. A symmetrical arrangem...
متن کاملRadially polarized passively mode-locked thin-disk laser oscillator emitting sub-picosecond pulses with an average output power exceeding the 100 W level.
We report on a high-power passively mode-locked radially polarized Yb:YAG thin-disk oscillator providing 125 W of average output power. To the best of our knowledge, this is the highest average power ever reported from a mode-locked radially polarized oscillator without subsequent amplification stages. Mode-locking was achieved by implementing a SESAM as the cavity end mirror and the radial pol...
